To all @0710172 t ma/ concern:

Be it known that. I, LAwRENon L, Jorrit soN, a subject of the King ofSweden, residing at Los Angeles, in the county of Los Angeles and Stateof California, have invented cert-ain new' and useful improvements inTire Cores, of which the following is a specification.

My invention relates to vehicle wheels, and the objects are, first, toprovide a solid tire that may be assembled into an outer tire casing;second, t-o provide interlocking fillers for an outer tire casing; and,third, to provide a tire rim that will clamp the said casing and fillerstogether and be mounted on a wheel felly in the customary manner.

Other objects and advantages will be made manifest in the followingspeciiication with an embodiment of the invention illustrated in theaccompanying drawings.

The invention consists of the arrangement of parts an embodiment ofwhich invention is also illustrated in the accompanying dra-wings, inwhich:

Figure l represents a sectional view of the tire and rim on line l--l ofFigure 2.

Figure 2 represents a sectional view of the wheel on line 2-2 of Figurel.

Figure 3 represents a developed inner circumferential view of theinterlocking fillers.

Figure l represents a side elevation of one of the fillers.

Referring to the drawing in which like characters of reference designatesimilar parts, the casing 1 being of an elastic material, is positionedon a circumferentially split rim 3--3, which rim is mounted on a felly4t. Fillers 2, 2'Ll and 9 are placed circumferentially end-toend withinsaid casing, there being only two fillers 2L which are placed betweenthe two end fillers 2, and only one filler 9 which is placed between thefillers 2a. In one end of each of the fillers 2 and 2L is formed aV-shaped groove 5, extending radially to the center of the wheel, and onthe other end of each filler is formed a corresponding tongue 6, whichtongues respectively fit in the grooves 5 of the adjacent fillers, asshown in Figure 3. fi recess 7, as shown in Figure 3, is provided in theinner side of each of the iillers 2"1 'to receive a spreader tool, notshown. rThe adjoining ends of the fillers 2a and 9 are also formed withV-shaped tongues 6 and grooves o, which tongues and grooves beingopposite one another on the two ends of the filler 9 are positionedparallel to one another as shown in Figure l.

rThe said fillers 2 and 2L are rst laid into the casing l with thetongues 6 and grooves 5 locled together as shown in Figure 3, and arepressed together by inserting a suitable spreader tool in the recesses7, to leave a suitable opening between the tongues Ga and grooves 5a toreceive the filler 9, and the tongues 6a and grooves 5a being parallelto one another as hereinbefore described, the said filler 9 may beinserted between the ad joining fillers 2a within the casing l, and whenthe said spreader tool is removed from the recesses 7 the fillers 2 and2a and 9 are permitted to expand and thus close the said tongue 6a andgroove 5a together also as shown in Figure 3. rlhe assembled casing land fillers 2, 2L and 9 are clamped together by pressing the joints 8together in the rims 3 and 3a, and the rims 3-3a are in turn mounted onthe felly 4 in the customary manner.

Having thus described my invention what l claim is:

ln a vehicle wheel, a casing split around its circumference, a pluralityof fillers in said casing, two of said fillers respectively at the endsof an intermediate filler having sockets to receive a spreader tool.
